描述

HIP4086 和 HIP4086A（亦称 HIP4086/A）是三相 N 沟道 MOSFET 驱动器。 这两款器件均专门用于 PWM 电机控制。 这些驱动器具有灵活的输入协议，用于驱动所有可能的开关组合。 对于开关磁阻应用，用户甚至可以覆盖击穿保护功能。 HIP4086/A 的可编程死区时间范围较宽（0.5μs 至 4.5μs），因此非常适合电机驱动器通常使用的低频（最高 100kHz）。 HIP4086 和 HIP4086A 的唯一区别是 HIP4086A 禁用了内置电荷泵。 该功能非常有利于需要安静 EMI 性能的应用（电荷泵工作频率为 10MHz）。 HIP4086 的优势在于内置的电荷泵可以无限延长高端驱动器的导通时间。 为确保高端驱动器启动电容器在开启前充满电，在首次应用 VDD 时会激活一个可编程启动刷新脉冲。 激活时，刷新脉冲会打开所有三个低端桥式场效应晶体管，同时关闭三个高端桥式场效应晶体管，以便为高端启动电容器充电。 刷新脉冲清除后，开始正常运行。 HIP4086/A 的另一个实用功能是可编程欠压设定点。 设定点范围从 6.6V 至 8.5V 不等。

This video discusses the HIP4086, 80V, 500mA, 3-Phase MOSFET Driver, at APEC 2013.

Transcript

Hello my name is Evan Jian. Today, I'm at APEC conference 2013 to introduce you to the HIP4086 BLDC three-phase motor drive demonstration board. This demonstration board provides you with a reference design for ebikes, battery powered tools and other applications using three-phase BLDC motor drive. The HIP4086 bridge FET drivers can independently control six-channel N-MOSFETs and also are specifically designed for low noise and improved EMI application. It has very low quiescent currents as well as fast turn on and turn off speed to reduce switch loss and improve efficiency. Also the device is very easy to configure. It provides the use of programmable UVL, dead time, bootstraps, refresh time, and so on.

This demonstration board has all sensors in supporting all possible switching logic. It has 5V buck regulators and 12V regulators to provide power for the MOSFET drivers and the microcontrollers and all sensors on this board. The reference design has a pre-programmed open loop control for the three-phase BLDC motor drive. It also provides an interface for users to modify the program.

Now, I'm going to demonstrate the functions of the demo board. There are four functions of this board. First we have start and stop function, if I push this button the motor will start to spin and there's a potential meter on this board but we can use a screw driver to adjust the motor spinning speed, speed up and speed down. You push the start stop button the motor will gradually slow down and then stop, start again. The second button is reverse function so I push this reverse function button the motor will gradually slow down and then reverse the rotating direction. Another button is the brake. I press it and immediately stop and the fourth button is reset. I push the reset button, the program in the microcontroller resets.

Thank you for watching this video.
